Manuel Fernando Bonilla Elhart (1868–1881) was a Peruvian child soldier and war hero who was killed by a grenade while fighting in the battle of Miraflores during the War of the Pacific.

He was a student at the College of Our Lady of Guadalupe when the War of the Pacific began between Chile and Peru, volunteering to join the Peruvian Army at the age of 13 to defend the city against the imminent Chilean Army.

In contrast to the occupying army of General Manuel Baquedano, the defense in Lima included civilians from different backgrounds and social classes.

Despite his injury, he grabbed a nearby rifle from a corpse and started firing,[2] being killed in an explosion caused by either a grenade[2] or a projectile,[1] with his body destroyed beyond recognition.
